F699 2rs Bearing Product Overview & Core Advantages
The F699 2rs is a metric single row deep groove ball bearing designed for reliable performance in compact spaces. Its key advantage lies in its sealed construction, which integrates nitrile rubber contact seals (2RS) on both sides to effectively retain lubricant and exclude contaminants. This design ensures long service life and reduced maintenance requirements, making it an ideal choice for applications demanding high reliability. The bearing is engineered to handle primarily radial loads and is manufactured to ABEC1 precision tolerance, providing consistent performance for a wide range of industrial uses.
F699 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| F699 | Basic bearing designation | Defines the core bearing dimensions: 9mm bore, 20mm OD, 6mm width. |
| 2RS | Bearing with rubber seals on both sides | Provides excellent contamination protection and lubricant retention. The nitrile rubber material offers good resistance to oils and temperatures up to 110°C. |
F699 2rs Bearing Structural Features & Performance Benefits
- Robust Construction & Load Capacity: Built from chrome steel rings and balls, this bearing offers a dynamic load rating of 472 lbf and a static load rating of 195 lbf, ensuring durability under radial loads.
- Optimized Internal Geometry: The deep groove raceway and 8 precision balls (3.175mm diameter) enable smooth operation and efficient load distribution.
- High-Speed Capability: The stainless steel cage maintains ball alignment and stability, contributing to a limiting speed of 34,000 rpm.
- Sealed for Life & Reduced Maintenance: The 2RS contact seals create an effective barrier against dust and moisture, making the bearing suitable for environments where re-lubrication is difficult. The standard MC3 radial internal clearance (0.002mm to 0.013mm) is well-suited for most general applications.
F699 2rs Bearing Typical Application Areas
The F699 2RS is widely used in various compact mechanisms and devices requiring reliable, sealed ball bearing performance. Common applications include:
- Small electric motors (e.g., cooling fans, power tools)
- Office machinery and computer peripherals
- Light-duty conveyor systems and pulleys
- Medical equipment and precision instruments
- Agricultural machinery components
